Taxonomy of Amauroderma (Basidiomycetes, Polyporaceae)
By João S. Furtado
Twenty-five species in this genus of tropical polypores are treated in this study. Included are notes on the characteristics of the basidiocarps and their taxonomic significance in Amauroderma. Two generic keys are provided: one based primarily on characteristics of the pilear cover, the other on features from macroscopic and microscopic observations.

I agree there may be some hastiness in assigning genera to so many of things currently labeled Amauroderma, or even Ganodermataceae. Who knows how many so-called Amauroderma are actually stipitate Microporellus ( It’s all loose sorting at the end of the day, since 90% of all observations lack either a vouchered specimen, sufficient information, or both.

Here is a tip

although I don’t know if a similar situation occurs in Europe. There is a thing here called Inter-library loan which I just discovered, but apparently it is quite well known. It means that if you are associated with a major institution (I am) and you find a book at the library of a major institution (say the online directories for Smithsonian Libraries or the Library of Congress), then you can request a book through your own institution and the other institution will fulfill it. Bingo! That means I do have access to great resources. I can’t send you books, but if you know of a title, I can probably get my hands on it and take a look. There may be more documentation than you think. In the meantime, I will check Corner for A. exile.

It is not only confusing…

… in fact there exists no book on Fungi in the Amazon region. The situation can not be compared to Europe or North America, where literature is abundant and DNA studies are common. Therefore the questions is rather: Who volunteers to do some basic field work and new descriptions? …and… How can such projects be funded?

The depicted ?Amauroderma? was much smaller and more delicate than others I have encountered. This might be quite characteristic. I have chosen A. exile as a species worth to consider when I get some literature in my hands. You seem to have far better resources.

In Ad Polyporaceas, 1984 sweated the details (particularly with the microscopic developement of the fruit body) to distinguish Ganoderma from Amauroderma and Humphreya. Although he does have a key in his books for various species he did admit that it is not possible to separate the groups in the field due to intergrading, etc. He studied these species for years and was confused, so why shouldn’t we feel the same? But he did not have DNA. Who volunteers to do a DNA study?
